The cutaneous sinus tract of maxillary dental origin is a rare but, a well-documented condition. However, several non-odontogenic disorders may also produce an extra-oral sinus tract. The diagnosis is a perplexity unless the treating operator considers the occurent of its dental origin. Such patients may undergo multiple surgical excisions and antibiotic therapy, but the treatment fails with the recurrence of the lesion, because the primary etiology is misdiagnosed. This case report describes a non-surgical endodontic therapy performed in relation with right maxillary first molar (# 16) which was misdiagnosed earlier. The confirmatory diagnosis was made by injection of radio-opaque contrast followed by Cone-beam computed tomography (CBCT) scan. The condition was diagnosed as chronic periradicular abscess with # 16 draining to an extra oral cutaneous sinus tract opening in right malar region. A successful outcome is observed after non-surgical endodontic treatment during follow-up of five years.
